Innovations in the soybean assortment

Abstract

In 2004, a large number of new soybean varieties and prospective lines were tested in a network of large-plot trials. Their agronomic characteristics were compared against standard varieties from corresponding maturity groups. Of 20 trials performed, 17 were located in the Vojvodina Province two in central Serbia and one in the region of Semberija. Thanks to favorable weather conditions, especially abundant rainfall, yields in the trials were high. Record yields were achieved in several locations. Differences were registered in yield performance among the varieties and lines. The favorable weather conditions suited the genotypes that a possessed high genetic yield potential. The variety Vojvođanka produced the highest average yield however, several newly released varieties showed deserving of being included in the commercial production. Among the early varieties, Valjevka and Bečejka were distinguished for high and stable yields in most regions. Average yields of the medium-maturing varieties were fairly uniform. Still, the variety Sava was best in the region of Bačka, Balkan, Zvezda and Tea in the region of Banat and the new line NS-L-210188 and the varieties Šapčanka and Balkan in the region of Srem, central Serbia and Semberija.

Tokom 2004. godine u mreži makroogleda testiran je veći broj novih sorti i perspektivnih linija, čija su agronomska svojstva upoređivana sa standardnim sortama soje, iste grupe zrenja. Uspešno je izvedeno 20 ogleda, lociranih uglavnom u Vojvodini (17), zatim centralnom delu Srbije (2) i u Semberiji (1). Zahvaljujući povoljnim vremenskim uslovima, naročito obilnim padavinama tokom vegetacionog perioda, prinosi u ogledima su uglavnom visoki, a u pojedinim lokalitetima rekordni. Uočene su razlike u prinosima između ispitivanih sorti i linija soje. Povoljni vremenski uslovi pogodovali su genotipovima visokog potencijala rodnosti. Najveći prosečan prinos ostvarila je sorta Vojvodanka, ali je i nekoliko novopriznatih sorti dokazalo da zaslužuju širenje u proizvodnji. Među ranostasnim sortama, visokim i stabilnim prinosima u većini regiona gajenja soje, izdvojile su se Valjevka i Bečejka, što ih preporučuje za širenje u proizvodnji. Prosečni prinosi srednjestasnih sorti i linija su vrlo izjednačeni, ali se uočava da je na području Bačke najbolje prinose ostvarila sorta Sava, u Banatu Balkan, Zvezda i Tea, a u Sremu, centralnoj Srbiji i Semberiji nova linija NS-L-210188 Šapčanka i Balkan.
